<p>PURPOSE:To reduce the quantity of waste water to be treated and to miniaturize the device by adding a part of waste water discharged from a wet type stack gas treatment device to the fuel (CWM) to be supplied to a combustion equipment to utilize it. CONSTITUTION:A large part of solids is separated and removed from the waste absorption liquid discharged from an absorption tower 3 in the wet type exhaust gas treatment equipment by a thickener 6, and a part of the supernatant water 8 in the thickener 6 is sent to a powdered coal slurry production unit 17 for the fuel supplied to a combustion equipment 1 for a boiler, etc., through a neutralization vessel 13. By this constitution, a part of waste water added to the fuel (CWM) is evaporated in the combustion equipment 1, and the contained substances are introduced with the stack gas into the wet type exhaust gas treatment device to be continuously absorbed and removed.</p> |
